Since the first formation of the famous "Peacock-Weakley" anions [Ln(WO)], a steady stream of breakthroughs have been made in the chemistry of multitalented lanthanide (Ln)-based polyoxometalates (POMs) for their potentially desirable properties. In particular, Ln ions are generally recognised as the "vitamins of the modern industry" owing to their ability to cover a wide emission range, endowing Ln-based POMs with great potential for versatile and diverse luminescence-related applications. In this frontier, we discuss the synthesis strategies and intramolecular energy transfer in Ln-based POM derivatives. Then, the progressive improvements achieved with Ln-based POMs in photoluminescence applications are highlighted, focusing mainly on luminescent and fluorescent probes. Finally, the challenges for Ln-based POM materials for photoluminescence applications are discussed.
自从著名的“孔雀-韦克利”阴离子[Ln(WO)]首次形成以来，基于具有潜在理想性质的多才多艺的镧系元素（Ln）的多金属氧酸盐（POMs）化学领域取得了一系列突破性进展。特别是，Ln离子因其能够覆盖广泛的发射范围而被普遍认为是“现代工业的维生素”，这赋予了基于Ln的POMs在多种与发光相关的应用中具有巨大潜力。在这个前沿领域，我们讨论了基于Ln的POM衍生物的合成策略和分子内能量转移。然后，重点介绍了基于Ln的POMs在光致发光应用中取得的逐步进展，主要集中在发光和荧光探针方面。最后，讨论了基于Ln的POM材料在光致发光应用中面临的挑战。
